Is this correct?

if you add
{$PPACKRECORDS C}

And make integer a longint (that is always 4 bytes, regardless of the mode you're compiling in), then it should be OK.

You can always compare with

#include <stdio.h>
#include <yourcheader.h>

int main () {

   printf("%d\n",sizeof(struct sockaddr_l));

}

and in pascal
writeln(sizeof(sockaddr_ll));

It seems OK, however, if you want portability too, you should:

uses
  ctypes;
{$PACKRECORDS C} // already commented by Michael
type
  sockaddr_ll = record
    sll_family: cushort;
    sll_protocol: cushort;
    sll_ifindex: cint;
    sll_hatype: cushort;
    sll_pkttype: cuchar;
    sll_halen: cuchar;
    sll_addr: array[0..7] of cuchar;
 end;

cheers
